The Ultimate Guide to Resolving Kmode Exception Not Handled Error in Windows

Key Takeaways

Disabling Fast Startup is usually an effective solution to resolve a kmode_exception_not_handled error. Alternatively, if you are able to identify the specific hardware that is triggering the error, updating its drivers can provide a more long-term resolution. In the event that you continue to encounter the kmode exception BSOD, it is advisable to perform a RAM test to detect any potential issues.

What Causes a Kmode Exception Error?

Encountering a distressing BSOD (Blue Screen Of Death) upon initiating or utilizing Windows can be quite disheartening. However, it is crucial to note that not all BSODs spell disaster. Fortunately, there's good news: resolving the Kmode Exception Not Handled error is a straightforward task that you can easily accomplish.

The "Kmode Exception Not Handled" error occurs when a kernel-mode program in Windows produces an uncaught exception. This error arises during the execution of a process, and the Kmode refers to a process that has full access to system memory and CPU instructions. It is specifically designated for critical components of the Windows system, including the CPU and attached devices.

In summary, this error occurs when a system component, typically a device driver, overwrites the memory of another component. Since the system fails to resolve this issue, an "unhandled" exception is triggered. While this error can occur in Windows 11, it is more commonly observed when using Windows 10.

How to Fix Kmode Exception Not Handled

Here are some effective methods to resolve the kmode exception not handled error in Windows. By following these solutions in the given sequence, you will increase your chances of fixing the issue with minimal frustration.

Before starting, take note of any file name shown within brackets at the conclusion of the kmode_exception_not_handled message on the error screen. This information, if available, will assist you in identifying the problematic driver at a later stage.

Disable Fast Startup to Fix Kmode Exception Error

Disabling Fast Startup can often resolve the kmode error, either temporarily or permanently. Fast Startup is a feature designed to accelerate the Windows loading process after shutdown or hibernation by preloading drivers. However, if the problematic drivers are included in this preloading, the error will persist.

To disable Fast Startup, you need to access the Control Panel. Search for and open the Control Panel, then navigate to "System and Security > Power Options." From there, select "Choose what power buttons do." Next, click on "Change settings that are currently unavailable" and uncheck the box next to "Turn on fast startup."

Please save the modifications and restart your computer. This action might resolve the kmode exception not handled error, or at least provide some relief so you can address the underlying issue, which could involve drivers that are either missing or corrupted.

Update the Problem Drivers to Fix Kmode Exception Not Handled

Assuming you want to permanently fix the problem, and be able to re-enable Fast Startup, you'll need to repair, update or replace the driver that is the likely cause.

To identify the hardware associated with the driver, conduct an online search using the displayed file name in the error message. It is important to note that outdated network drivers are a prevalent factor contributing to the kmode exception error. In order to proceed, navigate to Device Manager and search for the hardware related to the driver. Right-click on the corresponding device in the list and opt for "Update Driver" from the menu. Among the available options, choose "Search automatically for drivers."

It is anticipated that a suitable driver will be located, enabling you to proceed with the update. In the event that the search for the driver proves unsuccessful, it is recommended to explore the device manufacturer's website in order to acquire a new driver. Once obtained, the driver can be manually updated.

If the error message does not provide any clue to the cause, try checking for any devices that are listed as "Unknown Device." This may indicate that the driver for that particular device is missing or corrupted and needs to be replaced. To resolve this, you will need to delve into the device details, locate the hardware ID, and then conduct an online search to identify the device before proceeding with updating or replacing the drivers.

Stuck in a Kmode Exception Error Loop? Update Your Graphics Drivers

The kmode exception not handled error may sometimes occur in a recurring loop every time Windows restarts. Typically, this is caused by a driver error, possibly related to the display driver in this particular case. To resolve the issue, you should visit the website of your graphics card manufacturer (NVIDIA, AMD, or Intel) to download and install updated display drivers. To break free from the error loop, boot your system into safe mode and proceed with the installation of the newly downloaded driver. This should hopefully resolve the error loop.

If All Else Fails, Test Your RAM

In the event that none of the aforementioned solutions resolves the issue, it is possible that there is a problem with the memory, particularly with the RAM. Occasionally, the error message might explicitly mention RAM as the source of the problem, although this is not always the case.

Scan for RAM errors using the Windows Memory Diagnostic tool by searching and opening the tool from the Start Menu. Choose one of the two options to run the scan on restart. If any errors occur during the scan, it indicates a fault with your RAM.

To address this, shutdown your computer and securely reseat the RAM modules. Restart your PC and rerun the memory diagnostic. If the error no longer persists, the issue has been resolved. However, if the error persists, you may need to consider purchasing new RAM.
